I'm new to writing ado files, and I'm having some trouble.  I'd really
like my ado file to stop the processing of the calling do file if
certain conditions are met.  I guess "exit" just returns control to
the calling program.

Is there any way to make the calling program completely top based on a
condition encountered in the ado file?

Well, an ungraceful-but-effective way is to put

if `certain_conditions' exit = 1 // choose any informative nonzero integer here

in your called ado-file.  This will stop everything and return control to
Stata's command prompt.

But it might be better to have a little more coupling between your calling and
called ado-files than this.
